Trio surface maintenance

The trio grey dirt surface are hard wearing, but can suffer erosion after some heavy rain events.

Basic repair involves:

1. Scraping sediment in collection zones into small piles. This should be mostly dry.

2. Wetting down the surface for repair

3. Throwing dry sediment across the surface.

4. Brushing into a smooth layer.

5. Wetting lightly and riding.

An example is shown below.

This follows the grey dirt maintenance method described for the Dirt Jumps in another post.

Periodically, a more substantial repair using plate compaction should be considered.
